Company Overview


High Quality Design & Construction

Madison Development Group LLC (MDG) is a Seattle-based firm specializing in commercial and multi-family real estate development. MDG’s experience spans a broad spectrum of projects, from office to industrial, small retail projects to regional power centers and mixed-use properties.

We build many of our projects with the intent to hold, so no matter what the engagement, MDG is committed to high-quality design and construction and to upholding strong tenant relationships throughout the life of our projects.


Experience and Expertise

Our experienced team identifies obstacles before they become problems, and our innovative approach enables us to overcome challenges others are not willing to take on. We are problem solvers who maximize the marketability of difficult and underutilized properties.

We leverage our regional expertise and resourceful mind-set to successfully manage logistical and environmental issues and easily navigate building and permitting processes.


Hands-On Commitment to Every Project

In addition to over 65 years’ combined industry experience, principals Thomas Lee, Jim Gallaugher and Alan Cantlin bring a hands-on commitment to every project. Their involvement at every level has helped MDG develop strong, lasting partnerships with leading national retailers, such as Home Depot, Costco, Safeway and more.

Given our deep understanding of these national brands’ goals and processes, we approach a variety of development challenges with confidence.
